i rig my loft O2 with foot and it is very easy
we made this for all others our members who had lots of problems
to rig like gtx, vapor, and others, mostlyolder types of cam sails
and btw POC works with all type of pins becouse it have only
straight pin to fit any base or extension :)
and name, hahahaha, i supose that there are lots of funny name like
ours, but we think, POC is a cool name for that

thanx everybody for backing me up here and for join in discussion
@JP747POC have margins for part for downhouling, like picture you posted
in POC case the ARM can't go left or right without control, becouse
of that margins
